ROLL-POLISHER.

To'aZZ whom it may concern:

Be it known that we, Josnrn DANIELS and \VILLIAM I. SILVIS, citizens of the United States, both residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Roll-Polisher, of which the following is a specification.

Our invention relates to improvements in roll olishers for polishing the rolls of rolling mills and the like and has more particular reference to roll polishers of the character referred to which are adapted to be connected to the mill and operate continuously upon the rolls of the mill to constantly maintain the surface of the rolls in the proper condition and free from scale and the like.

The object of this invention is to provide a. roll polisher of the character mentioned which will be simple and inexpensive and illustrated in tie accompanying drawings' and particularly pointed out in the appended claims, it being understood that various changes. in the form, proportions, size and minor details of construction may be made,

provided they fall within the scope of the appended claims, without departing from tages of the invention.

It has been the custom heretofore in the operation of rolling mills such as sheet, tin and plate mills and the like to periodically shut down the mills for the purpose. of polishing the rolls to remove scales and abrasions from the surface of the rolls. It is generally understood by those skilled in the art that the rolls are very expensive and difficult to make and they must he handled with a great amount of care in order to produce the proper gage and quality of product when they are in operation. In order to ,turn out a product of the best quality the rolls must be operated as continuously as possible so that the temperature may remain substantially uniform,

- as when the rolls are cool the product is of inferior grade and uncertain gage. While in practical use the finely polished surfaces of the rolls become roughened, scratched and abraded and what is known as scales frequently form upon the surfaces thereof. As it is necessary that the product have a smooth and even surface the rolls must be maintained in proper condition to produce such a product and in the past it has been-customary to frequently polish the rolls in order to maintain them in the proper condition. The common way of polishing the rolls has been to discontinue rolling the product at frequent intervals and to manually polish the rolls by holding a-block of carborundum or similar material against the rolls or by'the use of a rotary grinding wheel which is ode ted to be temporarily clamped to the mill and brought into contact with the rolls. In order to polish the rolls with either these methods it is necessary to remove a of the attachments belonging to the in order that the rolls may be made accessible for the polishing operation and as this operation together with the polishing and subsequent assembling of the attachments requires considerable time the rolls are allowed to cool and much time is lost. The product of the. mill immediately after the rolls has been polished will be of an in ferior quality, owing to'the fact that the rolls are not sufficiently heated and by the time they have'been heated to the proper temperature the surfaces haveagain become more or less scratched and uneven so that at the time when the rolls are in the best condition as to temperature their surfaces have already lost their high polish. Thus,

---a ori the lower wall 10 of the under these conditions, the mill-is at no time capable of turning out a uniform product of the highest quality. A

It is the purpose of our invention to remedy this unsatisfactory condition by. -'-pi"oviding it upon the mill 'and to be constantly in opera- 7 polishing device to be attached tion, thus maintaining the surfaces of the rolls at all times. in a uniformly perfect condition and doing away with the necessity of frequently discontinuing rolling for' the The rolls In the construction lllustrated inthe ac companying drawings the housing of'a r011: ing mill of ordinary/construction is indicated by the numeral 1., The. upper and lower rolls 2 and 3 respectively are-of'the' usual construction and are mounted Within the housing in any common and well known -manner. I

Our'invention comprises primarily a polishing emery, polished steelor other suitable mateblock of carborundum, sand stone,

rial for the purpose intended, held in cone stant frictional contact with the surface of the roll, means being provided for properly distributing and -varying such contact as may be required. This polishing block is preferably made up of a plurality of sections 4 of p and held together bymeans to be hereinafter described. Each of the sections" 4' of the polishing block is provided upon its inner face with the two scraping edges 5 adapted to be held in contact with the'roll. purpose of avoiding creases or irregplari being formed upon the roll at t ies e point where the se'ctions 4 are'joined together, these joints are staggered,this result being accomplished' by forming a V-shaped notch 6 in one end of'each section and'beveled faces 7 upon the ppposite end of the section adapted to be received in the V -sh'aped notch of the next adjacent" section; These blocks are held firmly together and carried within a metallic frame 8 provided withend plates 9. The sections of polishing rame and are held firmly together by means of retaining blocks 11 and 12 formedof steel, iron; or other block ll is provided with a V-shaped notch 13 and the retaining end 14 in order p the contour ofthe ends of the adjacentsec tions of the polishing block. Each of the. blocks 11 and 12 is provided withacntral bore 15 being countersunk at 1 6 to accommodate the head 17 of the bolt 18, a set collar 19 being adapted to bef-rigidly secured upon taining .face of the roll a spring .tirie frame toward the roll so as to ri'n the form shown in the drawings For the ished. blocks rest Although the polishing block is suitable v material. The retaining block 12' with a beveled that they may conform to application I I in form and construction may be made, as

each bolt by means of a set screw 20, said set collar lying against the outer face of the reblock. Each-of the bolts 18 is provided with a screw threaded end 21 which is located through the screw threaded a erture 22 in the end plate 9 of the frame an 'a jam nut 23 is provided upon each bolt, a squared portion 24 being formed upon the" bolt for the purpose of applying a wrench or other 'tool for turning the same. For the purpose of holding the sections block at all times in contact with the sur- 25 is interposed between the rear face-of each section and the rear wall 26 of the frame. These springs are forthe purpose of compensating for any wear upon the scraping edges of the different sections of the polishin block. A bolt 27 and nut 28 are'provided or securing each of the springs 25 to the frame.

An an lar bracket 29 is provided upon the housing at either end of the roll and adapted to carry the polishing device, the.

frame 8 resting upon the shelf 30'of each bracket. A shaft 31 is journaled in the end plates 9 of the frame and is providednear each extremitywith an elliptical cam 32 rigidly secured upon said sha a ke 33. An operating handle 34 is also 'rigi y secured at one end of the shaft by means of the key 33 and adapted to engage a suitable rack bar 35. This cam arrange- .the en'- I all of the sections of the polishing block into contact with the roll in unison and this is accomplishe by means of the eccentric faces of the cams 32 being brought into contact with the veriica arms 36 of thebrackets 29. It will belun erstood that this polishin device is adapted to be permanently locate upon the mill, it only bcing'neoessary ,to adjust the polishing block with relation to the ment isfor the purpose of movin roll; Thid polisher does'not interfere with the work of turning out the product of'the mill and is continuously polishing the mile while they are in operation thus 0 viating the'necessity of frequently discontinuing theuse of the mill while the'rolls are being repolenerallv kept in contact with the surface 0 the ro time it is desired to move the block out of contact with the roll this may be accomplished by operation of the lever and cam "device.
